Core Advantages and Technical Highlights

Precise Protection:
The ABB 1SFB527068D7084 features a C characteristic tripping curve (5-10×In), making it ideal for circuits with moderate inrush currents like lighting and control circuits. The thermal-magnetic mechanism ensures reliable protection against both overloads and short circuits.

High Breaking Capacity:
With a 6kA breaking capacity at 230/400V AC, this MCB can safely interrupt high fault currents, protecting downstream equipment and wiring from damage.

Durable Construction:
The robust thermoplastic housing withstands mechanical stress and environmental factors. The silver-nickel contacts ensure long electrical life and reliable performance.

Easy Installation:
The screw terminals accept a wide range of conductor sizes (1-25mm²) and provide secure, vibration-resistant connections. The compact 1-module width (17.5mm) saves space in distribution boards.

Safety Features:
The 1SFB527068D7084 includes finger-safe terminals and a clear ON/OFF indication. The trip-free mechanism ensures protection even if the handle is held in the ON position during a fault.

Standards Compliance:
Certified to IEC/EN 60898-1 standards, this MCB meets international requirements for circuit protection in residential and commercial applications.
